Measuring factor productivity has been important in economics since its early days as a scientific discipline for a number of reasons. The first is the availability of systematically collected agricultural data after World War I, which allowed researchers to motivate and test newly developed...

In this paper we examine the role of the interaction between labour productivity and the use of factors in explaining the recent (1998-2007) 11% decline in wheat production in China. We employ a non-neutral stochastic production frontier approach that enables us to identify the interaction and...
